Lights
At The 2019 Burning Man Decompression Party
Old Power Station
San Francisco, California
The main source of light on Earth is the Sun. Sunlight provides the energy that green plants use to create sugars mostly in the form of starches, which release energy into the living things that digest them. This process of photosynthesis provides virtually all the energy used by living things. Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps. With the development of electric lights and power systems, electric lighting has effectively replaced firelight.

Fire As A Form Of Light, At The 2019 Burning Man Decompression Party, Old Power Station, San Francisco, California Fire has been used by humans in rituals, in agriculture for clearing land, for cooking, generating heat and light, for signaling, propulsion purposes, smelting, forging, incineration of waste, cremation, and as a weapon or mode of destruction.[from wikipedia] |

Fire Tornado, As A Form Of Light, At The 2019 Burning Man Decompression Party, Old Power Station, San Francisco, California The phenomenon is sometimes mislabeled a fire tornado, firenado, fire swirl, or fire twister, but these are a separate phenomenon where a fire has such intensity that it generates an actual tornado. (This phenomenon was first verified in the 2003 Canberra bushfires.) Fire whirls are not usually classifiable as tornadoes as the vortex in most cases does not extend from the surface to cloud base.[from wikipedia] |

Lights Generally, At The 2019 Burning Man Decompression Party, Old Power Station, San Francisco, California An electric light is a device that produces visible light from electric current. It is the most common form of artificial lighting and is essential to modern society, providing interior lighting for buildings and exterior light for evening and nighttime activities. In technical usage, a replaceable component that produces light from electricity is called a lamp.[from wikipedia] |

Lights Out, As A Form Of Non-Light, At The 2019 Burning Man Decompression Party, Old Power Station, San Francisco, California Darkness, the polar opposite of brightness, is understood as a lack of illumination or an absence of visible light. Human vision is unable to distinguish color in conditions of either high brightness or high darkness. In conditions with insufficient light levels, color perception ranges from achromatic to ultimately black.[from wikipedia] |
